Inclined PLane Force problem

  1. Mar 2, 2008 #1
    1. The problem statement, all variables and given/known data
    An engine is used to pull a train of two cars out of a mine. The floor slopes upward at an angle of 22 degrees. Each car has a mass of 1.1x10^4 Kg and normally travels without friction on the tracks. The engine can exert a maximum force of 1.6x10^5 N on car A. If the engineer again throttles back so that the force exerted by the engine on car A decreases at the constant rate of 2.9 N per second, how long before the train stops moving up the track? Assume the original speed was 3.4 m/s

    2. Relevant equations
    F= Fmax-2.9t

    3. The attempt at a solution
    incase u havnt realized we're solving for "T"
